I was under the (mis?)impression that under Mojave, TRIM was supported for external SSDs connected via Thunderbolt.
I have a 2015 27" iMac running 10.14.3, with a Thunderbolt 2 enclosure with a Samsung 850 EVO SSD. System report says that TRIM is NOT supported.
Is there something I need to do to turn on TRIM on the external SSD?

This should work. In macOS Terminal enter the following command:
sudo trimforce enable
It will prompt for a password (must be administrator to do this) and it
should enable TRIM on all third party drives.
Note that this will not work on USB devices.
